Advanced Diagnostics.
Advanced diagnostics investigates vehicle faults and engine health using checks and diagnostic information before deciding on further work. It is for European car owners seeking to understand a problem or assess a vehicle before modifications. Etuners offers diagnostics in Smithfield, Western Sydney by appointment; the investigation scope and any follow-up repairs must be confirmed.
How is a fault diagnosed from data?
Most workshops diagnose by reading fault codes and replacing parts until the light goes out. We work the other way: because we calibrate ECUs for a living, we read the same live data the engine computer sees — hundreds of parameters at once — and trace the fault to its actual cause before touching a single part.
That means faster answers, fewer replaced parts, and problems that stay fixed. It's also why every tune we deliver starts with a diagnostic baseline: we never add power to an engine we haven't first proven healthy.
What We Diagnose
From stubborn intermittent faults to full pre-purchase health reports, every job ends with data you can see and a straight answer.
Complex Fault Diagnosis
Intermittent misfires, limp modes, phantom warning lights — the problems other workshops give back unsolved. We diagnose from live data, not guesswork.
- Intermittent fault tracing
- Limp mode & DTC analysis
- Electrical & sensor diagnosis
- No parts-cannon guesswork
Pre-Tune & Pre-Purchase Checks
Before we add power — or before you buy a car — we verify the engine is healthy. Compression, fuel trims, boost integrity, and misfire history, all documented.
- Pre-tune baseline logging
- Pre-purchase inspections
- Compression & leak-down tests
- Written condition report
Deep Datalog Analysis
We log and analyse hundreds of engine parameters at once — fuel trims, timing corrections, boost behaviour, and knock activity — to find what a scan tool can't see.
- Multi-channel datalogging
- Knock & timing analysis
- Fuel system health checks
- Boost leak detection
Tuned Elsewhere? We Can Still Help
Car not running right after work done somewhere else? We regularly diagnose vehicles tuned or modified by other workshops. We'll log it, tell you exactly what's wrong, and give you an honest path to fixing it.
The Process
01 — Describe the Symptom
When it happens, how it feels, and what's been tried — the history matters.
02 — Log & Analyse
Live datalogging on the road or dyno to capture the fault in the act.
03 — Report & Fix
A clear explanation of the cause, the evidence, and exactly what it takes to fix.
Diagnostic sessions are booked by the hour with a clear estimate upfront. Tell us the symptoms and we'll take it from there.
